HAIR-GURLING DEVICE.

Applcaton'led January 3, 1925. Serial No. 324.

This invention relates to hair curling devices and more particularly to electrically operated curling' devices adapted tor producing in huinan hair so called permanent waving.

One ot the principal objects oi this invention is to provide a curling device in which the possibility oit burning out the electric heatingv wires, due to the operators neglil0 gence7 is practically eliininated. Another object is to provide an apparatus ot this character in which the hair niay be lrept under a regulated tension during the socalled bakingv process. tor the purpose ot enpediting the operation and producingr a incre lasting wave-effect. il. further object is to provide a curling,r device in which the heat and steain generated duringthe baking process are carried away troni the scalp or' the patient, thereby greatly adding to the latters comfort. Still another object is to provide a simple device ot relatively low cost ot manufacture having siinple ineans for quickly gripping the tutt ot hair which is about to be curled and for holdingv said tutt with increasing' pressure as it is directed toward a central curling barrel7 forming part ot the device. Additional features and advantages ot this invention will appear troni the following description considered in connection with the appended drawing forming a part oit this application. `The purpose ot this application is especially to cover certain new iinproveinents not shown in a now pending application for Letters -Patent on the `saine subject matter, tiled September 8. 192i, and bearing the Serial Number 736,509.

Reference beinp; had to the drawing, my hair-curling; device comprises two principal parts, namely, the heating eleinent H and the curling-element C. The i'oriner is coinposed ot a metal tube l secured at the torward and the rear end in the collars 2 and 3 respectively, made ot thermo-electric insulating material. This tube is covered intermediate said collars with a layer oi inica 4f upon which a coil ot electrical heating wire 5 is wound, through which a current of electricity may be circulated. This heating wire is protected outwardly with a covering 6, preferably oi. asbestos, 'tor the purend of the pose ot reducing the loss ot heat through radiation to the outside. rlhe collars and correlated parts are assembled within a Sleeve 7 of insulating` material ofsuch inside diaineter as to leave an air space 8, to reduce the heating ot said sleeve. A suitable number ot apertures 9 are provided in the latter to enable the escape of heated air frein, and the entrance ot cold air into, said space.

Diafnietrically disposed on the collar 3 are the inwardly directed switch-clips 16 and 17 inade ot' resilient metal and secured by ineansv et screws 18. These clips are provided at their inner ends with arcuate contact surfaces 19, tor a purpose to be eX- plained later.

Laterally secured in suitable grooves onsaid collar, and at right angles to the switchclips are the connectors 82 and 83 niade ot metal and each provided with an inward hoolr portion 84 engaging the inner tace ot the collar. Said connectors are slightly bent toward the center ot the heating element and are each provided adjacent their outer ends with a transverse slot 85. An aperture 86 is also shown in each connector to receive a serevv 87; by means olwhiclrthe collar and connector Aare securely lheldwto the sleeve member 7.

As shown diagrammatieally inliig, the switch-clip 16 and the connector 83 are electrically connected by means',ot-awire09 and the ends 2l and 22 of the heating coil 5 are respectively conneetedtoiithe connector 82 and the switch-clip 17.

T he irear f end .of Lthe yheating` lelement is also provided Vwith azremovable cap 28 of linsulating material, havinga central aperture 24 for slidably reeeivingand guiding the flexible electrie cab-le i241, and a series o fzconeentrically:disposed vholes25 'which 'acilitate :.theieseape fot .heat .and steam Y:away

'llhe yforward end O' said Ashank is slotted to term twe resilient lingers 39 which are each provided at the Yforward end with the flat l portions l0 and the beads del.

@n the rear end et the tube 35 are cut a series 'et notches 42, of 'right-,angled tri- .angularfshape, lwhich are:engaged by cer-V respendingly shaped teeth 412 provided lin S0 the hu 4:3 ot the Piange lily the whole jtori g a ratchet connection allowingxthefrotan et thesaid engagedparts inone direc- `tion venly.

Placed within 'the curling barrel is a 85 spindle -45 havingat the rear `endaa'short threaded stud de Vscrewed into l the flange A144C, albedyfportien l? iittingy snugly in a bushing ffl-8, inserted inthe hub 43, 'and in theit-ube 3l.

This `disc Yis preferably lniurled and is Imade'slightly smaller than the inside diameter of said -sleeverand'has a central aperture suitably threaded to receive the Ashort threaded stud 57 ofthe switch-plug; 58,the end-otiwhich is preferably taperedf to facilitate its insertion Vbetween Athe contact surfaces oit-fthe -switclrclipsle and .17.y .The-stede? is made; shorter thanthethi (ness of the dise'to 4prevent ;an,f''electrical connection between the switch-plug andthe ether'metallicgparts oit the curling` element.

The hair-,grinning element, which also acts as a head-pretecter against the :heat generated within the curlingV device,is com Ypesed ettheeuter disc 59, the intermediate disc GO vand the inner disc 6l,- all-:three dises being properly held together'by Ameans of :rivets 162-anda pivot-pin 63 upon which is rotatably mounted *the 'hair-pijl ipping` wheel 64,'positiened intermediate the outerand inner discs in a circularrecess 65 out in the-invtermediate dise 60.

ln the'euter disc 59 and the innerrdisc 6l are cut respectively the curved openslotsie and 6T of suitable widthnandconcentrlcally 130 disposed around the pivot-pin 63. These slots are so arranged as to register with an arcuate recess 68 cut in the periphery of the gripping wheel, when the latter is properly rotated.

The inner disc has two diametrically djsposed recesses 69 cut in its periphery to allow for the passage of the bent portion 70 of the hoog-member 32. A` rectangular central aperture 71 is also provided to snugly receive the flattened portions 40 of the curling-shank which may be snapped into said aperture owing to the resiliency of the fingers 39.

ln the intermediate disc are also cut two arcuate slots 72 and 73 disposed concentrically and diametrically opposite, and of sufcient width to permit the insertion therein of the bent portion of the hook-member. The length of these slots is such as to permit a suficient rotation of the whole gripping member to enable the bent portion of the hooked member to fully engage the periphery of the inner disc, thereby holding said gripping member against the sealing washer 29 at the forward end of the heating element. At the center of the intermediate member is also provided a rectangular aperture 74 which registers with the similar aperture 71 in the inner disc, but which is made longer in order to provide ample room for the beads 41 on the curling shank,

' and to enable the resilient fingers thereof to assume their normal position after insertion through the inner disc, thereby forming a good snap-connection between the curling element and the hair-gripping element.

A feather-spring 7 5 is secured in the slot 7 6 provided in the intermediate disc to operate against the linurled periphery of the gripping wheel to hold the latter in any selected position.

The curling device is applied by ator in the following manner A tuft of hair of suitable size is first laid into the recess 68 of the gripping-wheel held close to the scalp, and the former is then turned by the operator to gather the tuft in the curved slots 66 and 67 and grip it firmly as it approaches the center of the grippingmember. rlhe curling element is then snapped into the central aperture of the. grippingmember and the tuft of hair is wrapped around the curling element in a clock-wise sense (as seen by the operator and if the ratchet teeth are as shown in the drawing) and the free end of the tuft is tied to the curling element by means of a string. The coiled tuft is now enclosed in a strip of damp cloth. such as flannel, which is wrapped around in the same sense as the hair. When so arranged, the coiled hair is put under additional tension by rotating the disc-centralizer in a counter-clock sense, while t-he tubes 34 and 35 of the curling barrel are held an operagainst rotation by'pressing with the fingers of the other hand at the place of junction 36 of said tubes. lhen the desired tension is obtained, the hold at the junction is released, the result being that' the tube 35, under the action of the stressed coil-spring 50, will exert a constant tension on the coiled tuft of hair in the same direction in which the latter was wound.

The heating element H, which is connected to a source of electric energy by means of a line-plug 77, is pushed over the curling element until the bent portions of the hookinembers 32 enter the recesses 69 provided in the gripping-element. The heating element H`is then given a slight twist to cause the hoch-elements to securely hold the gripping-member against the sealing-washer 29,

thereby preventing the escape of steam against the scalp. By so doing, the switchplug 58 is forced between the contact surfaces of the switch-clips 16 and 17 and a closed circuit for the passage of electric current in the heating-coil is established, as will be readily understood by referring to Fig. 2.

As the process of baking lasts several minutes, and in order to save time, the complete device, when applied, is suspended by means of a suspension ring 78 slidably engaging the outer sleeve 7 and fastened to a cord '79 passed over a pulley 8O and having a counter-weight 81 tied at the other end. Vhile the baking-process is going on, one or more tufts of hair may be prepared on additional curling elements, as suggested in F ig. 12.

Upon completion of the baking process, the operator removes the heating element by first twisting it to disengage the hook-members from the gripping-member and then pulling it away from the curling-member, thereby breaking the engagement of the contact-plug with the switch-clips. The electric current within the heating wire is therefore interrupted and all danger of burning said wire, due to the operator forgetting to turn off the electric current at the line switch, is eliminated.

As will be understood, there may be slight changes made in the construction and arrangement of the details of my invention without departing from the field and scope of the same, and I intend to include all such variations, as fall within the scope of the appended claims, in this application, in which the preferred form only of my invention has been disclosed.
